Extraction replica method from thinned transmission electron microscopy samples without floating off carbon films: A case study on reduced activation steel

Journal of Microscopy, EarlyView.
Abstract A recipe for producing carbon extraction replicas from twin‐jet electropolished disks is described. This technique allows tracking the analysed region with respect to the bulk sample. An example use of the method as applied to a reduced activation ferritic martensitic (RAFM) steel, ‘UK‐RAFM’, is reported.

The effect of retained austenite on austenite reversion behavior and corresponding mechanical properties of Ti–Mo precipitation hardening stainless steels

Although the ageing process is the most important metallurgical process influencing the austenite reversion reaction, the role of retained austenite existing after cryogenic treatment on austenite reversion transformation is still not fully explored ...

Evidence of a local BCC‐type coordination of cobalt in FCC taenite of iron meteorites

Meteoritics &Planetary Science, EarlyView.
Abstract Ni, Co, and Fe K‐edge X‐ray absorption fine structure (XAFS) measurements were performed, revealing an unexpected local structure around Co in well‐known iron and stony‐iron meteorites. Cobalt is enriched in kamacite but remains in taenite at concentrations of at least 0.3 atom%.

A Proof of Principle for the Phase‐Dependent Electrocatalytic Activity of NiTi Shape Memory Alloys for the Oxygen Evolution Reaction

ChemElectroChem, Volume 13, Issue 12, 17 June 2026.
We compare martensitic (Ni50Ti50) and austenitic (Ni51.2Ti48.8) NiTi shape memory alloys at room temperature as oxygen evolution reaction (OER) anodes, demonstrating that phase‐dependent microstructure governs electronic conductivity, surface roughness, and wettability.

Effect of free surface on martensitic transformation in individual retained austenite grains

, 2015
The stability of retained austenite depends on the chemical composition, morphology, grain size and hardness of the surrounding matrix. Different to these aspects, the present work explores the effect of free surface on the stability of retained ...

Evaluation of Mechanical, Thermal, Rheological, and Biocompatibility Properties of Additively Manufactured Metal‐Reinforced Biocomposites Optimized by Reinforcement Ratios and Printing Parameters

Polymer Composites, Volume 47, Issue 11, Page 10258-10281, 10 June 2026.
Schematic illustration of PLA/316L stainless steel composite filament production via fused deposition modeling, demonstrating the trade‐off between stainless steel content, mechanical enhancement, and biocompatibility. ABSTRACT Polylactic acid (PLA) is a biodegradable thermoplastic widely used in biomedical devices; however, its inherent brittleness ...

Characterization of Nitinol Produced by Laser Powder Bed Fusion for Mechanical Metamaterial Applications

Advanced Engineering Materials, Volume 28, Issue 11, 3 June 2026.
Stabilization of L‐PBF Ni50.7Ti49.3 under low‐cycle loading was investigated. Recoverable strain after cycling was dependent on the amount of applied load. Recovery ratio was 53.4% and 35.1% at intermediate and high load, respectively. The maximum total strain reached 10.3% at a high load of 1200 MPa.
